Abstract

A nonwoven fabric main body (11) that constitute a nonwoven fabric (1) according to the present invention is composed by integrating composite polyester fibers (2) and flame-retardant acrylic fibers (3) which serve as other fibers making up the balance. The composite polyester fibers (2) have a sheath-core structure wherein a sheath part (4) is composed of a low-melting-point polyester and a core part (5) is composed of a high-melting-point polyester that has a higher melting point than the low-melting-point polyester. The composite polyester fibers (2) are contained in an amount of 15-80% by weight in a total of 100% by weight of the nonwoven fabric main body (11). The apparent density of the nonwoven fabric main body (11) ((weight of nonwoven fabric main body) / (thickness of nonwoven fabric main body)) is from 0.005 g / cm3 to 0.040 g / cm3. In addition, the bending resistance of the nonwoven fabric main body (11) in the flow direction of the fibers is 50-220 mN.cm, while the bending resistance in a direction that is orthogonal to the flow direction is 20-140 mN.cm.

Description

technical field [0001] The present invention relates to a non-woven fabric and a filter using the non-woven fabric, in particular to a non-woven fabric and a filter using the non-woven fabric for preventing pollution of range hoods, ventilation fans, air vents, etc. . Background technique [0002] Conventionally, nonwoven fabrics made of synthetic fibers have been used as filters for preventing contamination of range hoods and ventilating fans. [0003] For example, Japanese Patent Application Laid-Open No. 2003-236320 discloses a non-woven fabric and a filter using the non-woven fabric. After the fibers are mixed to form a fiber web (also called a web (card)), the fiber web is given a binder (adhesive, bonding agent) formed of a flame-retardant thermoplastic resin for bonding between fibers by using a sprayer or the like. ) to manufacture. A flame retardant such as a phosphorus-based water-soluble flame-retardant compound is added to the binder. When such a filter is use...
